Description
Technical Field
The utility model relates to an instrument of measurement instruction, especially manometer for gas.
Background
The pressure gauge is a meter which takes an elastic element as a sensitive element and measures and indicates the pressure higher than the ambient pressure, is very commonly applied and almost extends to all the fields of industrial processes and scientific researches. The pressure gauge is based on the principle that the pressure is displayed by the rotation of a pointer as the pressure deformation is transmitted to the pointer by a conversion mechanism of a movement in the gauge through the elastic deformation of a sensitive element in the gauge. For non-corrosive gas, the existing sensitive element of the small pressure gauge is basically a copper bourdon tube, one defect of the copper bourdon tube is that the volume must be increased if the range is increased and the pressure is applied, so the volume of the pressure gauge with the copper bourdon tube is limited in range or volume, and in addition, the copper bourdon tube is complex to process, needs precise welding, and is easy to leak.
Disclosure of Invention
Aiming at the defects in the prior art, the invention provides the radial high-pressure gauge, in the application, the sensitive element of the pressure gauge is changed into the spiral tube from the bourdon tube, and meanwhile, the contact mode of the spiral tube and the core is changed, so that the measuring range of the pressure gauge is greatly increased on the premise of small size change amplitude of the pressure gauge, and the application range of the small pressure gauge is wider.
In order to solve the technical problem, the invention is solved by the following technical scheme: radial high-pressure gauge, including the casing, be provided with the copper support in the casing, be provided with fluid passage in the copper support, characterized in that, the casing in be provided with the reference column, the reference column on the activity be provided with the spiral pipe, the inside cavity of spiral pipe, one end opening other end seals, the spiral pipe open end intercommunication fluid passage, the contact of spiral pipe blind end is fixed core on the copper support, core swing joint has the pointer.
Among the above-mentioned technical scheme, preferred, the core include core main part, tensile connecting rod and package vexed head, the core main part rotates to be connected tensile connecting rod one end, the vexed head of package rotates to be connected the tensile connecting rod other end, the contact of spiral pipe blind end is covered vexed head.
In the above technical scheme, preferably, the plug comprises a groove portion and a connecting portion, the connecting portion is connected with the stretching connecting rod, the groove portion is provided with a groove, and the closed end of the spiral pipe extends into the groove and contacts with the groove portion.
In the above technical solution, preferably, the open end of the spiral pipe is welded to the fluid passage.
The bourdon tube is widely used for small pressure gauges due to small volume and high sensitivity, but the upper limit of the measuring range of the bourdon tube is low, and the bourdon tube is not as good as a spiral tube pressure gauge, but due to low sensitivity of the spiral tube, if no complex movement is arranged, the accuracy of the spiral tube is not good when the bourdon tube is used for low pressure. And this application has changed the contact mode of spiral pipe with the core, uses tensile connecting rod and the vexed head of package to enlarge the spiral pipe sensitivity through lever principle, under the condition that does not change whole volume, lets the very big increase of range of manometer for the small-size manometer measuring range of part extends to high-pressure from the low pressure.
Compared with the prior art, the application makes under the little prerequisite of manometer volume size variation range, very big increase the range of manometer, lets small-size manometer's application scope more extensive.

Detailed Description
The present invention will be described in further detail below with reference to specific embodiments and the attached drawings.
Example 1: as shown in fig. 1 to 3, a radial high-pressure gauge comprises a casing 1, a cover 2, a dial 3 and a dial 4, wherein a copper support 5 is arranged in the casing, a fluid passage is arranged in the copper support 5, and the copper support is fixed in the casing 1 through a bolt. Be provided with core 6 on the copper support 5, core 6 include core main part 61, tensile connecting rod 62 and package vexed head 63, casing 1 in be provided with reference column 7, reference column 7 go up the activity and be provided with spiral pipe 8, the inside cavity of spiral pipe 8, spiral pipe one end opening other end seal, spiral pipe 8 open end intercommunication fluid passage, the welding of spiral pipe 8 open end on the fluid passage. The machine core main body 61 is rotationally connected with one end of the stretching connecting rod 62, the covering head 63 is rotationally connected with the other end of the stretching connecting rod 62, and the closed end of the spiral pipe 8 is in contact with the covering head 63. The covering choke plug 63 comprises a groove part and a connecting part, the connecting part is connected with the stretching connecting rod 62, a groove is formed in the groove part, and the closed end of the spiral pipe 8 extends into the groove and contacts with the groove part. The movement 6 and the indicator plate 4 are fixed on the copper support 5 together through bolts, the movement 6 is movably connected with a pointer 9, the pointer 9 is arranged on the dial plate 3, and a pointer limit is arranged on the dial plate.
During the use, gaseous follow fluid passage gets into spiral pipe 8, and spiral pipe 8 rotates under the gas pressure effect, spiral pipe 8 seals and drives package vexed head 63 when removing, and under the effect of tensile connecting rod 62, core main part 61 atress this moment lets pointer 9 instruction pressure.
